.16/ An engine pumps a liquid of density 'dcontinuously through a pipe of area of crosssection A. If the speed with which the liquidpasses' through a pipe is v. then the rate atwhich the Kinetic energy is being impartedto the liquid is(A) Adv3/2 (8) (12)Adv(c) Adv2/2 (D)Adv2tnhich

Answer»

Rate of liquid flow =(1/2*m*v^2)/tRate of flow =m/tRate of flow=dV/tRate of flow=dAL/t1/2* d*A*v *v^21/2 *dAv^3
